Description

Anorganische BuntpigmenteInorganic colored pigments

Die vorliegende Erfindung betrifft flokkulationsstabile Buntpigmente mit guter Korrosionsschutzwirkung.The present invention relates to flocculation-stable colored pigments with good corrosion protection.

Es ist bekannt anorganische Pigmente mit anorganischen oder organischen Substanzen nachzubehandeln, um ihre Eigenschaften für bestimmte Anwendungsgebiete zu verbessern« So kann beispielsweise die Dispergierbarkeit bestimmter Pigmente in Kunststoffen durch aluminiumoxidhaltige Nachbehandlungsmittel gefördert werden« Die Nachbehandlung mit einer Mischung aus Sojabohnenphosphatiden und Inosit-Phosphatiden (US-Patentschrift 3 017 282) ermöglicht die Herstellung von Eisenoxiden mit verbesserter Korrosionsschutzwirkung; derartig behandelte Pigmente sind jedoch nicht flokkulationsstabil.It is known to post-treat inorganic pigments with inorganic or organic substances in order to improve their properties to improve certain areas of application «For example the dispersibility of certain pigments in plastics by aftertreatment agents containing aluminum oxide "Post-treatment with a mixture of soybean phosphatides and inositol phosphatides (US patent 3,017,282) enables the production of iron oxides with improved corrosion protection; treated in this way However, pigments are not flocculation-stable.

Anorganische Buntpigmente neigen nach der Dispergierung in einem Lack oder einer Dispersionsfarbe oft dazu, sich wieder nachträglich zu größeren Aggregaten zusammenzulagerno Be^. diesem Vorgang - Flokkulation genannt - werden Farbton, Deckvermögen und Glanz der Pigmente verändert und beeinträchtigt. Die Tatsache, daß ein Pigment einen hohen Dispersionsgrad be-Inorganic colored pigments, after being dispersed in a varnish or emulsion paint, often tend to rearrange again to form larger aggregates o Be ^. This process - known as flocculation - changes and adversely affects the color tone, hiding power and gloss of the pigments. The fact that a pigment has a high degree of dispersion

sitzt, impliziert notwendigerweise nicht eine hohe Flokkulationsstabilität. Die gut dispergierten Pigmentteilchen können zusammenstoßen und sogenannte Flokkulate bilden. Flokkulation ist im wesentlichen ein dynamischer Vorgang, nämlich eine Folge des Wechselspiels zwischen den anziehenden Kräften bestimmter dispergierter Partikel und der willkürlichen Bewegung der Moleküle Inder flüssigen Phase infolge der Brown'schen Molekularbewegung. (G.D. Parfitt, Dispersion of powders in liquids, 1969, S. 165, Elsevier Publishing Company Limited, Amsterdam, London, New York)does not necessarily imply a high level of flocculation stability. The well-dispersed pigment particles can collide and form so-called flocculates. Flocculation is essentially a dynamic process, namely a consequence of the interplay between the attractive ones Forces of certain dispersed particles and the arbitrary movement of the molecules in the liquid phase due to the Brownian molecular motion. (G.D. Parfitt, Dispersion of powders in liquids, 1969, p. 165, Elsevier Publishing Company Limited, Amsterdam, London, New York)

Die Zudosierung kann daher in Schmelze, aber auch in Gegenwart eines Lösungs- oder Emulgiermittels erfolgen.The metered addition can therefore take place in the melt, but also in the presence of a solvent or emulsifier.

Die Stelle im Produktionsgang des Pigmentes, an der die erfindungsgemäß verwendeten Mittel dem Pigment zugefügt werden, ist nicht von entscheidender Bedeutung.The point in the production process of the pigment at which the invention The agent used is added to the pigment is not of critical importance.

Die Behandlung kann durchgeführt werden, indem die organische Substanz in Schmelze, gelöst oder emulgiert dem unbehandelten oder gegebenenfalls anorganisch nachbehandelten Pigment vor oder während der Endmahlung z.B. in einer Stift-, Kugel-, Pendel- oder Strahlmühle zugegeben wird.The treatment can be carried out by putting the organic substance in melt, dissolved or emulsified to the untreated or optionally inorganically aftertreated pigment before or during the final grinding, e.g. in a pencil, ball, Pendulum or jet mill is added.

Die Prüfung der Flokkulationseigenschaften in Lackkunstharzbindemitteln erfolgte mittels einer Chromatographietestes und des sogenannten "rub-out-Tests". Die Prüfung des Korrosionsverhaltens erfolgte im Salzsprühtest. Die Prüfung der Farbtonverschiebung erfolgte durch visuellen Vergleich von durch Spritzen aufgetragenen Lacken, die mit den erfindungsgemäß nachbehandelten bzw. nicht nachbehandelten PigmentenTesting the flocculation properties in lacquer synthetic resin binders took place by means of a chromatography test and the so-called "rub-out test". Testing the corrosion behavior took place in the salt spray test. The hue shift was checked by visual comparison of lacquers applied by spraying which contain the pigments after-treated or not after-treated according to the invention

Chromatographietest und "rub-out-Test": Beim Chromatographietest werden die Flokkulationseigenschaften durch Eintauchen von Chromatographie-Papier in dem zu untersuchenden Lack bestimmt. Ist das im Lack enthaltende Pigment flokkuliert, so steigt nur noch das Bindemittel in das Papier. Tritt keine Flokkulation ein, so wandert auch das Pigment in das Papier, (s. Farbe und Lacke, 76, 351-358, 1970).Chromatography test and "rub-out test": In the chromatography test, the flocculation properties determined by immersing chromatography paper in the paint to be examined. Is the pigment contained in the paint flocculates, only the binder rises into the paper. If there is no flocculation, the pigment also migrates in the paper, (see Farb und Lacke, 76, 351-358, 1970).

Der "rub-out-Test" ist ein üblicher in der Lackindustrie verwendeter Test und ermöglicht eine weitere Prüfung des Flokkulationsverhaltens. Nach diesem Test wird das zu untersuchende Pigment in einem geeigneten Bindemittel a^uf einer Glasplatte in dünner Schicht aufgebracht. Der noch feuchte Lack auf der Glasplatte wird danach mit dem Finger gerieben. Ist das Pigment flokkuliert, so werden die Flokkulate beim Reiben durch Scherung zerstört, wobei sich der Farbton gegenüber der nicht geriebenen Fläche ändert.The "rub-out test" is a common one used in the paint industry Test and enables a further test of the flocculation behavior. After this test, the pigment to be examined is in a suitable binder on a glass plate applied in a thin layer. The still wet paint on the glass plate is then rubbed with the finger. is If the pigment flocculates, the flocculates are destroyed by shearing on rubbing, the hue being opposite the surface that has not been rubbed changes.

Die folgende Tabelle 1 enthält eine Zusammenstellung der Ergebnisse der durchgeführten Versuche und Vergleichsversuche nach dem Chromatographie- bzw. "rub-out-Test". Als Bindemittel wurde sowohl ein langöliges als auch ein mittelöliges Alkydharz verwandt.The following table 1 contains a summary of the results of the tests carried out and comparative tests after the chromatography or "rub-out test". Both a long-oil and a medium-oil alkyd resin were used as the binder related.

Die Prüfung des Korrosionsverhaltens erfolgte an Tiefziehblechen und gebonderten Blechen im Salzsprühtest. Auf diese Bleche wurden Grundierungen auf der Basis eines handelsüblichen styrolisierten Alkydharzes, das das zu untersuchende Pigment enthielt, aufgebracht und getrocknet. Die Prüfung erfolgte gegen ein unbehandeltes Vergleichspigment nach ASTM S 117-64 bzw. DIN 50021The corrosion behavior was tested on deep-drawn sheets and bonded sheets in the salt spray test. To this Sheets were primers based on a commercially available styrenated alkyd resin, which is the one under investigation Pigment contained, applied and dried. The test was carried out against an untreated comparison pigment ASTM S 117-64 or DIN 50021

Die Benotung der Korrosionsschutzwirkung erfolgte nach einer visuellen Beurteilung der Bleche nach der Behandlung im Salzsprühtest. Es wurden den Proben Wertnoten von 1-5 zugeordnet: The rating of the corrosion protection effect was carried out after a visual assessment of the sheets after treatment in the salt spray test. The samples were given scores from 1-5:

1 = sehr gut, 2 = gut, 3 = befriedigend, 4 = ausreichend, 5 = ungenügend. Der Test gewährleistet bei einiger Routine recht gut reproduzierbare Ergebnisse.1 = very good, 2 = good, 3 = satisfactory, 4 = sufficient, 5 = inadequate. The test ensures quite a bit of routine easily reproducible results.
